It is one of the largest Ethereum digital asset wallets. Millions of people use it because of how safe, secure, and easy the user interface is.
This was before the 2.5 version update which now supports BTC, ETH, ATM, EOS, TRX, CKB, BCH, LTC and other digital assets. It also enables decentralized value exchange and dapp browsing in one place, as well as some amazing features to add such as token swap options, hardware wallets and more cool features.
With these additions, there is no doubt that it will soon become the largest digital asset wallet in the world.
